Claims
exact text as granted — not AI-modifiedWe claim:
1. A trans-(±)-2,4,6-permissibly substituted octahydropyrimido[4,5-g]quinoline of the formula: ##STR20## wherein R is H, CN, C 1-3 alkyl O--CO, C 1-3 alkyl or allyl; R 1 is NH 2 , NHR 3 , NR 4 R 5 , R 2 is H, CH 3 , Cl or Br; R 3 is methyl, ethyl or n-propyl, C 1-3 alkyl-CO, phenyl-CO or substituted phenyl-CO, wherein said substituents are 1 or 2 members of the group: chloro, fluoro, bromo, methyl, ethyl, methoxy, ethoxy and trifluoromethyl; R 4 and R 5 are individually methyl, ethyl or n-propyl; and pharmaceutically acceptable acid addition salts thereof.
2. A trans-(-)-2,4,6-permissibly substituted octahydropyrimido[4,5-g]quinoline of the formula ##STR21## wherein R is H, CN, C 1-3 alkyl O--CO, C 1-3 alkyl or allyl; R 1 is NH 2 , NHR 3 , NR 4 R 5 , R 2 is H, CH 3 , Cl or Br, R 3 is methyl, ethyl or n-propyl, C 1-3 alkyl-CO, phenyl-CO or substituted phenyl-CO, wherein said substituents are 1 or 2 members of the group: chloro, fluoro, bromo, methyl, ethyl, methoxy, ethoxy and trifluoromethyl; R 4 and R 5 are individually methyl, ethyl or n-propyl; and pharmaceutically acceptable acid addition salts thereof.
3. A compound according to claim 1 in which R is methyl, ethyl, n-propyl or allyl, R 1 is amino or acetamino and R 2 is H or Cl.
4. A compound according to claim 2 in which R is methyl, ethyl or n-propyl, R 1 is NH 2 or acetamino, and R 2 is H or Cl.
5. A compound of the formula ##STR22## in which R 1 is NH 2 , NHCH 3 , N(CH 3 ) 2 , NH--CO--CH 3 or NH--CO--phenyl, R 2 is H, Cl, Br or CH 3 and R 6 is C 1-3 alkyl or allyl.
6. A compound according to claim 5 in which R 1 is NH 2 or NH--CO--CH 3 , R 2 is H or Cl and R 6 is n-propyl, and pharmaceutically-acceptable salts thereof.
7. A compound according to claim 2 in which R is C 1-3 alkyl or allyl.
8. A compound according to claim 2 in which R 2 is H.
9. A compound according to claim 2 in which R 1 is NH 2 .
10. A compound according to claim 2 in which R is n-propyl.

18. A compound according to claim 2, said compound being trans-(-)-2-amino-6-n-propyl-5,5a,6,7,8,9,9a,10-octahydropyrimido[4,5-g]quinoline.
19. A compound according to claim 1, said compound being trans-(±)-2-acetamino-6-n-propyl-5,5a,6,7,8,9,9a,10-octahydropyrimido[4,5-g]quinoline.
20. A compound according to claim 1, said compound being trans-(±)-2-amino-4-chloro-6-n-propyl-5,5a,6,7,8,9,9a,10-octahydropyrimido[4,5-g]quinoline.
21. A hydrochloride salt of a compound according to claim 2.
22. A salt according to claim 16, said salt being trans-(-)-2-amino-6-n-propyl-5,5a,6,7,8,9,9a,10-octahydropyrimido[4,5-g]quinoline dihydrochloride.
